T0 all whom t may concern Beitknown that I, GEORGE T. McLnoD, a citizen of the United States, residingat Dedhampin the county of Norfolk and State of have invented an Improvement in Top-Lift Scallopers or Concavers, of` which the following description, in" connection with the accompanying drawings, is`

a specification, .like letters-on the drawings representing like parts.`

The invention herein to `be described i relates to machines for cutting the breast portion ofboot and shoe heels and more particuf larly for scallo-pingor concaving the breast edge of the toplift. i

The aims and purposes of the present in-V vention aieto provide a machine oi the generaltype mentioned which shall be simple in construction, eilicient in operation,` and wherein uniformity of product may be at` tained, all as will moreiully appear from the following description and accompanying drawings of one `form of means for carrying theinvention into practical effect.`

nieans andreceiving the sliding portion 8 of the `bracket 9, the. upper portion whereof` is havinga slot,` ;11` through which passes `the clamping screw.

provided with a `face piece 10 112. The clampingl` screw ,12 is screwthreaded into the bracket or Work lport 13, the connectiontbetween port 13 being provided with `as for instance the `gib 14, ,'wherebywupon loosening the clamping screw 12 the bracket :or Work slide support 13 may be adjusted with respect to the facepiece l0 for a purlpose that will presentlyappear.`

y 1 The bracket orwork slide support 13 has at top and bottom the flanges 15 which forni` slide 16,2Figs.

"suitable -guideways for a work `2 and 3, a springl?, connected at `one end tothe pin 18 secured tothe slide, and at the. i other end` to a suitable pint19 connectedtof the bracket or work slide "support, tending normallyto` move the work slide to the right, from the bracket 13 is a- Fig. 2; Proj ectin g lug 20, through which is screwtlireaded `the adjusting stopQli-khaving `a hand` wlieelj22 the construction beingsuch that, asfthe work `slideds retracted `by `means. of its `springs 17, the endthereof will contact with slide sup`` s the ffacez piece 10 andthe bracket or work slide sup-` guiding means,v

the end of the adjusting stop 2l and limit,

movement responsive to saidsprings. i

`l\1[ounted in a suitable bracket 23, Figl, is lan adjusting, device, preferably in the form of athreaded pin24` having a hand Wheel 25,1

and screw-threaded into the bracket, the` construction beingsuch that, upon rotation Iof the handwheel the bracket 9, and per` p and Workslide supe. port 13 secured thereto, may be movedlnl a` force `its face piece l0 `diagonal direction transversely of the cutter i shaft, as Will be readily understood.

From the construction thus far described it will be` seen that the work slide 1G is sup-i` ported to slide on the bracket 13 in.a direc-` tion diagonalito the cutter shaft and sub-` stantially parallel to the cutting edges of the cutter blades, as indicated inFig. 2.

Secured to the work slide is a `heel supporting plate 2G, thc supporting surface oi?.` to the cutting edges ofl so that if the` which is at an angle the cutter blades, see Fig. 2, heel be supported upon said heel supporting plate, as indicated Fig. 2, the breast at `S by dotted lines` in` line of the {heel maybe so: disposed with respect to the cutting blades that the latter may remove from the breast edge Vof the toplift a portion thereof to provide the scalloped or c'oneaved effect, ask indijustably secured to the outer surface porstops maybe properly so that when l will occupy positions act` as gaging tions of the recessed-plates or `boxes 31 are the heel breast stops 32, 32, each `of which is connected adjustably to its recessed plate or `box` by means of slot and screw connec-y tions, as indicated at 33, Fig. 4t,fthe `conthat the heel breast adjusted with relation to their carrying element.

Secured to each of the heel breast stops 32 struction being such isa wing portion `34, the rearwardly ei;-v tendingends of which are widened, Fig. 2,-r

to properly embrace and guide a heel between them and to give an extended bearing for the sides of'said heel, 'as indicated in Fig. 2. f

Each" of the breast stop carriers 29 is preferably formed as an arm and is provided with a pin or roll 35 adapted to engage suitably shaped cam guides or grooves bracket or workslide support. The'cam guides or grooves 36 are preferably formed converging toward the cutter end of the work slide support, as indicated in Fig. 3,

the work slideis vin its retracted or normal position with its end resting against the adjusting stop 21', Fig. 2,

the rolls 35 of the breast stop carriers will be separated, :and perforce the breast gages near to each.' If, under these conditions, a heel wider than the distan-ce between the breast stops be moved over the face of the heel plate between the wing portionsof the stops, it will causer the breast stopstoseparate,'and the rolls 35, being thus caused to ap roach each other, travel down the converging `guides 36 and cause the'work carrying `slide to move longitudinally until the breast of the heel meets ther breast stops 327 whereuponl `further movement of the heel over the heel plate and toward the cutter is arrested, the heel being at such time in properl scalloping position. I

From the construction described it will be noted that the act of placing the heel in working position causes longitudinal inovement of the work slide, and that the breast stops, by engagement with the heel breast, `means for determining not heel is in proper scalloping Only when the but also the longi position on the heel plate,

formed onthe relatively stationaryv tioning a heel nearer to or farther from the end of the cutter. lt will be obvious, of course, ythat the particulars of' structure, whereby, breast stops the work'slide nieves to place the heel indesired position with relation to the cutter, may be variously formed or designed within the true scope of the invenfA tion; and it is also obvious that owing to the angular relationl of the heel plate and work slide, that movement of the slide might in some cases occur as a result of pushing the heel over the heel plates and such force might, at times, cooperate with the breast gages as they separate to move the-Work slide longitudinally, `but primarily the 'act of separating the breast gages effects such movement as the heelismoved to working position.

,The work slide 16 may be limited in its longitudinal movement toward the end Aof theV cutter and as one means for such limitation, the cam guides or grooves 36 causev the rolls 35 to come together at the -junc` ture of said guides or grooves, though obviously any usual stop might be employed.

Since the cutter blades and heel supporting plate are related, as indicated in Fig. 2, it follows that the length of the cut 27, Fig. 5, made in the breast edge of the toplift will depend upon the part of the cutting blades which acts upon the heel when the latter is in its iinal cutting position, so that should the heel reach its final cutting positie-nat a point nearer the base of the cutting blades, or to the right7 Fig. 2, the length of the cut 27, will be less than if such position is reached at' a portion of the blades nearer` their outer ends, as will be obvious. IThe longitudinal adjustment of the bracket or work slidesupport 13, as hereinbeforepointed out, will enable the length of the cut 27 to bevaried, as described, and likewise the adjustment of the bracket 9 transversely of the cutter shaftwill enablethe depth of the cut 2"(y to be varied without at the same time varying the length.

From the described construction as one embodiment ofthe present invention it will b e apparent that the scallop or concave cut 2T formed in the breast edge of the toplift may be variously formed, lthat is, it may be made longer and deeper or it may be made vdeeper without being at the same time elongated.

The heelv supporting plate 26 maypreferably have its edge 37, Fig. 1-, concave to insure non-interference with 'ther cutting blades;v and obviously various changes'may `be made in the vparticular means employed tudinal movement of the work slide in posivstop 2l so that when the work slide as the heel is moved. against the..

is in its normal or retracted position, the breast gages are closer together than the width of the narrovvest or smallest heel to be treated. IIe likewise adjusts the bracket 9, and perforce the Work slide support, by means of the adjusting screw 24: and `in accordance with `the depth of cut desired; and, if necessary, `he may move the work slide support or adjust it longitudinally to regulate thelength of cut tofbe made. `The operative then places the tread surface ofthe heel on the heel plate and moves the heel between "the Wing portions of the breast stops., Since the breast stops are too `close together to .admit ythe heel freely, they sep-arate as the heel is pushed to Working position and until the breast finally brings up against the hooks of the breast stops. This separating movement of the heel breast gagesmovesthe rolls toward each other with the result that the` Work slideis moved longitudinally until the heel is arrested by the breast stops, at

which timethe 4heel .Will be in position for treatment. vWhen the` heel is removedthe spring -l'Tmoves the `Work slide to `initial positionfagainst the back stop 2l.
